The pvd coating machine PVD technology can be applied to the processing and manufacturing of marine supplies, jewelry, handicrafts, door and window hardware, kitchen and bathroom hardware, lamps, marine supplies, jewelry, handicrafts, and other decorative products. The application is very extensive. Many customers are also very interested in the relevant knowledge when purchasing equipment. Today, we have gathered into a small vacuum series to introduce the general knowledge of pvd coating machine PVD coating, I hope to help everyone improve their relevant knowledge and skills.

The specific principle of PVD coating (ion coating) technology is to use low voltage and high current arc discharge technology under vacuum conditions. Gas discharge is used to evaporate the target material and ionize both the evaporated substance and gas. The acceleration effect of the electric field is used to deposit the evaporated substance and its reaction products on the workpiece.

The characteristics of PVD coating film. The film coated by PVD coating technology has the characteristics of high hardness, high wear resistance (low friction coefficient), good corrosion resistance and chemical stability, and the service life of the film is longer; At the same time, the film layer can significantly improve the appearance and decorative performance of the workpiece.

PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron level coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (TiN, ZrN, CrN, TiAlN), carbide films (TiC, TiCN), and oxide films (such as TiO). Thickness of PVD coating layer - The thickness of PVD coating layer is in the micrometer level, with a relatively thin thickness, usually 0.3 μ m~5 μ m. The thickness of the decorative coating layer is generally 0.3 μ m~1 μ m. Therefore, various physical and chemical properties of the workpiece surface can be improved without affecting the original size of the workpiece, and there is no need for further processing after plating.

The types of colors that PVD coating can produce - Currently, the colors that PVD coating can produce include deep golden yellow, light golden yellow, coffee, bronze, gray, black, gray black, seven colors, etc. By controlling the relevant parameters during the coating process, the color of the coating can be controlled; After the coating is completed, the color can be measured using relevant instruments to quantify the color and determine whether the coated color meets the requirements.

At present, pvd coating machine PVD coating technology is mainly used in the industry. The application of PVD coating technology is mainly divided into two categories: decorative coating and tool coating. The main purpose of decorative plating is to improve the appearance, decorative performance, and color of the workpiece, while making it more wear-resistant and corrosion-resistant and extending its service life; This is mainly applied in various fields of the hardware industry, such as door and window hardware, locks, bathroom hardware, and other industries. The main purpose of tool plating is to improve the surface hardness and wear resistance of the workpiece, reduce the friction coefficient of the surface, and improve the service life of the workpiece; This aspect is mainly applied in various cutting tools, turning tools (such as turning tools, planers, milling cutters, drill bits, etc.), various hardware tools (such as screwdrivers, pliers, etc.), and various molds and other products
